MAINTENANCE

Lights

Headlight and taillight lenses become dirty during normal operation. 

Clean all lights frequently to ensure a clear field of vision as well as 

visibility to other vehicles.
When servicing a halogen lamp, don't touch the lamp with bare fingers. 

Oil from your skin leaves a residue, causing a hot spot that will shorten 

the life of the lamp.

LED Headlamps (if equipped)
If a headlight becomes damaged or inoperable, the entire headlight 

assembly must be replaced.

Tip: If an LED headlamp has moisture or fogging inside, disconnect the wiring 

harness from the headlamp(s) for a few days to allow the moisture to clear 

out. Do not operate the vehicle at night or in low light conditions without 

properly working headlights.

Brake Lights

When the brake pedal is depressed, the brake light comes on. Check the 

brake light before each ride.
1. Turn the ignition switch to the HEADLIGHTS ON position.
2. Apply the brakes. The brake light should come on after about 10 

mm (0.4 in.) of pedal travel. If the light doesn't come on, check the 

bulb.

Taillight/Brake Light/Turn Signal Lamp Replacement

1. Remove the harness 

connector from the back

Headlight Beam Adjustment

1. Place the vehicle on a level surface with the headlight 

approximately 25 ft. (7.6 m) from a wall. Place the transmission in 

PARK.

2. Measure the distance from the floor to the center of the headlight 

and make a mark on the wall at the same height.

3. Apply the brakes. Turn the ignition 

switch to the HEADLIGHTS ON 

position.

4. Observe the headlight aim. The most 

intense part of the headlight beam 

should be aimed 8" (20 cm) below the 

mark placed on the wall in step 2. 

Include the weight of a rider on the seat 

while performing this step.

5. If adjustment is necessary, turn the 

headlight adjustment screw to adjust the 

beam.

6. Repeat steps 4-5 until the beam is 

properly adjusted.
